After shooting Anderson, Barnes fired at another ranger before fleeing into the woods. After an extensive manhunt, Barnes was found the following day in a creek. An autopsy showed he drowned.

Police say Barnes showed signs of erratic behavior since returning from Iraq. They believe Barnes fled to the park after shooting and injuring four people at a house party in Seattle earlier that evening.

Admission to the park was free on Saturday. The flag remained at half-staff, and a small memorial for Anderson was at the rangers' kiosk.

Anderson left behind her husband, who also worked at the park, and two children. A candlelight vigil will be held in her honor on Sunday.
